How can enzyme activity be inhibited
WebIn biochemistry, allosteric regulation (or allosteric control) is the regulation of an enzyme by binding an effector molecule at a site other than the enzyme's active site.. The site to which the effector binds is termed the allosteric site or regulatory site.Allosteric sites allow effectors to bind to the protein, often resulting in a conformational change and/or a … Web26 de jan. de 2024 · The cold plasma technique has emerged as a novel, economic, and environmentally friendly approach that reduces the expression of ripening and browning enzymes while increasing the activity of antioxidant enzymes; microorganisms are significantly inhibited, therefore improving the shelf life of fruits and vegetables.
